  • Publication number: 20100305996
    Abstract: A method for the computer-aided automatic creation of timetables for transportation systems takes into account time limits, which are used in the framework of planification tools and online for the planning of timetables as a component of control systems. The invention broadens the method for creating timetables as described in WO 97/09218 (German patent application DE 195 33 127). The object of the invention is to ensure that in particular upper time limits are regarded as operational boundary conditions. A non-linear model of penalty costs is used to achieve this object.
